Abstract (en)
[origin: WO9516158A1] A control valve (1) is disclosed, having a housing (2) which has an input port (3) and an output port (4) that are connected to one another by a flow path in which a throttling device is arranged. It is desirable for such a control valve to be able to hold a volume flow constant, irrespective of the load pressure at the output port (4). For that purpose, the throttling device comprises a series connection of a first throttle (27), the passage of which is externally adjustable, and a second throttle (28), the passage of which is adjustable in dependence on pressure.
